<p>@RabbitListener 可以标注在类上面，需配合 @RabbitHandler 注解一起使用。</p>
<p>使用 @RabbitListener 注解标记方法，当监听到所指队列 中有消息时则会进行接收并处理</p>
<p>@RabbitListener 标注在类上面表示当有收到消息的时候，就交给 @RabbitHandler 的方法处理，具体使用哪个方法处理，根据 MessageConverter 转换后的参数类型</p>
<p><code>@RabbitListener(queuesToDeclare = @Queue(&quot;hello&quot;))</code>给queuesToDeclare赋值声明队列 <code>@Queue</code>创建队列</p>

<p>通过查看源码我们可以得知默认队列属性是<code>durable=true,exclusive=false,autoDelete=false</code></p>
